Note the lifters - these are the best - beware of lifters that do not look like these.
I have NOS lifters that are exactly the same as what I am offering,and these are the only ones I use in my engine builds
Lifters are not RAIV lifters, but regular HP replacements that will still operate to 6000 RPM
